>cd02957 Phd_like Phosducin (Phd)-like family; composed of Phd and Phd-like proteins (PhLP), characterized as cytosolic regulators of G protein functions. Phd and PhLPs specifically bind G protein betagamma (Gbg)-subunits with high affinity, resulting in the solubilization of Gbg from the plasma membrane and impeding G protein-mediated signal transduction by inhibiting the formation of a functional G protein trimer (G protein alphabetagamma). Phd also inhibits the GTPase activity of G protein alpha. Phd can be phosphorylated by protein kinase A and G protein-coupled receptor kinase 2, leading to its inactivation. Phd was originally isolated from the retina, where it is highly expressed and has been implicated to play an important role in light adaptation. It is also found in the pineal gland, liver, spleen, striated muscle and the brain. The C-terminal domain of Phd adopts a thioredoxin fold, but it does not contain a CXXC motif. Phd interacts with G protein beta mostly through the N-te
